Calibration - ICP DAS USA I-8014W User Manual

Calibration

Every one of I-8014W is factory calibrated and well verified. Usually, it is unnecessary
to calibrate the module, unless the input impedance is changed on a calibrated
module, or the accuracy is lost.
To calibrate the I-8014W, in addition to plugging the I-8014W in the slot of controller,
the following items are needed:
●
One stable calibration source such as 3 1/2 digit power supplier (or better) or a
battery output.
●
One 4 1/2 digit voltage meter (15-bit resolution or better)
●
Calibration Program: see
demo program.
Tips & Warnings
1. An unstable calibration source will cause the calibration fault and
affect the data acquisition accuracy.
2. If you would like to calibrate ± 20 mA, select ± 2.5V instead, the
two types use the same gain and offset values.
3. The calibration program use channel 0 to accept calibration
source only.
